| 20090066742 | PRINTHEAD WITH INCREASING DRIVE PULSE TO COUNTER HEATER OXIDE GROWTH - An inkjet printer that has a printhead with an array of ejection devices for ejecting drops of liquid onto a media substrate. Each of the ejection devices having a chamber for holding liquid, a nozzle in fluid communication with the chamber and a heater positioned in the chamber for contact with the liquid such that resistive heating of the heater generates a vapour bubble that ejects a drop of the liquid through the nozzle. The printer also has a controller for receiving print data and generating drive pulses to energize the heaters in accordance with the print data. The controller increases the drive pulse energy during the printhead lifetime. | 03-12-2009 |
| 20100128090 | Mems Bubble Generator Incorporating Superalloy Heater In Direct Contact With Bubble Formation Liquid Without Intervening Protective Coating - A MEMS vapor bubble generator includes a chamber for holding liquid; and a heater positioned in the chamber, the heater being formed using a sputtering technique. The heater is formed from a superalloy material. The superalloy material of the heater is in direct contact with the liquid, without any intervening protective coating. The superalloy has a crystalline structure with a grain size less than 100 nano-metres. The superalloy is MCrAlX, where M is one or more of Ni, Co, Fe with M contributing at least 50% by weight, Cr contributing between 8% and 35% by weight, Al contributing more than zero but less than 8% by weight, and X contributing less than 25% by weight, with X consisting of zero or more other elements, preferably including but not limited to Mo, Re, Ru, Ti, Ta, V, W, Nb, Zr, B, C, Si, Y, Hf. | 05-27-2010 |
| 20110122183 | PRINTHEAD INCORPORATING PRESSURE PULSE DIFFUSING STRUCTURES BETWEEN INK CHAMBERS SUPPLIED BY SAME INK INLET - An inkjet printer includes a printhead having a plurality of ink chambers fed be an ink inlet, each ink chamber having a heater element for ejecting drops of ink from a nozzle aperture of each chamber; a plurality of pressure pulse diffusing structure positioned between the plurality of ink chambers fed by the ink inlet, the plurality of pressure pulse diffusing structures for retarding a propagation of pressure waves generated by each ink chamber to adjacent ink chambers; and a controller for receiving print data and generating drive pulses to energize the heater elements in accordance with the print data. The controller increases the drive pulse energy during the printhead lifetime such that the drive pulse energy is never less than that of a preceding drive pulse. | 05-26-2011 |

| 20090012080 | Sirtuin modulating compounds - Provided herein are novel sirtuin-modulating compounds and methods of use thereof. The sirtuin-modulating compounds may be used for increasing the lifespan of a cell, and treating and/or preventing a wide variety of diseases and disorders including, for example, diseases or disorders related to aging or stress, diabetes, obesity, neurodegenerative diseases, cardiovascular disease, blood clotting disorders, inflammation, cancer, and/or flushing as well as diseases or disorders that would benefit from increased mitochondrial activity. Also provided are compositions comprising a sirtuin-modulating compound in combination with another therapeutic agent. | 01-08-2009 |
| 20110009496 | RESVERATROL FORMULATIONS - Resveratrol can be used to treat or inhibit the onset of many diseases that are related to the aging process, but large doses are required. The present invention provides concentrated liquid formulations of resveratrol, typically having a resveratrol concentration of at least 10% by weight. These formulations improve patient compliance because the patient need not consume such a large volume of a resveratrol formulation. | 01-13-2011 |
| 20110015192 | SIRTUIN MODULATING COMPOUNDS - Provided herein are novel sirtuin-modulating compounds and methods of use thereof. The sirtuin-modulating compounds may be used for increasing the lifespan of a cell, and treating and/or preventing a wide variety of diseases and disorders including, for example, diseases or disorders related to aging or stress, diabetes, obesity, neurodegenerative diseases, cardiovascular disease, blood clotting disorders, inflammation, cancer, and/or flushing as well as diseases or disorders that would benfit from increased mitochondrial activity. Also provided are compositions comprising a sirtuin-modulating compound in combination with another therapeutic agent. | 01-20-2011 |
